I did a search and didn't find anything on this, but apologies I just happened to miss is and people already know about it.

Anyway, I just discovered Sketch Theatre last night. It's a really cool website where different videos of different artists doing their thing are shown, so you can see the process of different artists and different styles. It also exists as a way to tell young aspiring artists just what you can do as an artist, career wise. It's a lot of fun to just go through the different videos. Check it out!
